Appendix E: Infrared Methane Sensors

Appendix E describes the Eagle’s non-standard, infrared methane sensor. This appendix also offers additional information for calibrating and replacing the infrared methane sensor.

Target Gases

The infrared methane sensors are setup for and factory-calibrated to methane. This section lists other combustible gases known to respond and to not respond to the infrared methane sensor. Consult RKI Instruments, Inc., for combustible gases not listed below.

The following combustible gases are also known to respond to the infrared methane sensors.

•ethane

•hexane

•IPA

•isobutane

•MEK

•propane

•toluene

The following combustible gases are known to not respond or respond poorly to the infrared methane sensor.

•acetylene

•hydrogen

•styrene

Speciﬁcations

Table 13 lists speciﬁcations for the infrared methane sensor. The alarm settings are user-adjustable (see “Updating the Alarm Point Settings” on page 32.)

Table 13: Infrared Methane Sensor Speciﬁcations

Range	Alarm 1	Alarm 2	TWA Alarm	STEL Alarm
0 to 100% LEL CH4	10% LEL	50% LEL	N/A	N/A
PPM (1)	5000 ppm	25,000 ppm	N/A	N/A
0 to100% Volume CH4	10% VOL	20% VOL	N/A	N/A

(1)The PPM range for CH4 is 0 to 50,000 ppm.
